All Implemented Interfaces:

Mapping

public class InClassNameClassIndicator

extends InValueClassIndicator

Determines the class of database records using a column holding the class name, and limits SELECTs using an IN (...) statement. This mapping initializes the possible subclasses with a SELECT DISTINCT on the class column, and thereafter assumes it has a complete list of subclasses to work with.

Method Summary

protected Class	getClass(Object indicator, ClassLoader loader) Return the class for the given column value.
protected Object	getClassIndicator(ClassMapping mapping) Return the value the column should take.
protected int	getDataStoreTypeCode() Return the FieldMapping type code for the type of data stored by this indicator.
String	getMappingType() Return the abbreviated name of this mapping, or the full class name if it is a custom mapping.
void	loadSubclasses(JDBCStoreManager store) Initialize the subclass list for our base class.
